IM'PROVED STAVE-.MAKING MACHINE.

Specification forming part of Letters Patent No. 10,596, dated Novemberv17, 1863; antedated November 11, 1863.

To all whom it may concern.'

Be it known that we, ALVY T. BARNS, JOHN B. BARNs, and SOLOMON. BARNs,all of Groesbeek, in the county of Hamilton and State of Ohio, haveinvented a new and useful Improvement in Stave-Making Machines; and wehereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings and lettersv of reference marked thereon, which form part ofthis specification.

Our invention is intended to cut the staves of the proper length, todress them on the i11- side and on the outside, and nally to dress theedges to the proper bevel. The various devices for these purposes arearranged side by side on one bench, and will be described in orderbelow.

In order that others duly skilled may be enabled to understand andconstruct and use our invention, we shall proceed to describe it l indetail.

In the accompanying drawings, Figure l is a perspective drawing of thecomplete Inachine. Fig. 2 is a vertical transverse section through thatportion of the machine designed for dressing the edges ol' staves. Fig.3 is a vertical longitudinal section through that portion ot' machinedesigned for dressing the inner and outer sides of staves. Fig. 4 is aplan of bits or knives for dressing in and out sides of staves.

Like letters of reference designate like parts in all the drawings.

A A are the two main pieces of bench, joined by the bolts c d, andsupported by the braces b b b b and base-pieces B B. C is a longitudinalrail for the attachment and support ot' pedals, and also forstrengthening and staying .the bench. Two upright stays, C O, arefastened to rear main piece A and longitudinal rail C, for theattachment of pedals and for stil'ening the entire bench.

The machinery for cutting the staves of the proper length will first bedescribed.

D is a shaft or spindle, journaled in boxes c c, (supported by bench AA,) havin g a flywheel, E, keyed on its outer end, and on its inner eX-tremity, as on a mandrel, carrying a small circular saw, F. 0n themiddle, or thereabout, of the spindle is the toothed pinion G, which,be-

ingl in gear with a toothed wheel, G', below, receives motion therefrom.vThis wheel below is keyed on a shaft, properly journaled, and having acrank, c', on its inner end. To this crank the pitman-rod d is attached,and b v means ofthe pedal H, to which the other end of pitman-rod islinked, the circular saw is set v in motion by the foot of operator.Alongside of the circular saw on the bench two guides, I I, aresecnred,and on the inner side each guide is grooved. In these grooves thegageframe J slides. On this frame an iron gagerod, K, is secured with astop or gage, K', in the form of a clamp attached thereto by aclamping-screw, f., The staves being already riven out are singly placedon the gage-fra1ne,(which has previously been set to the requiredlength,) and the circular saw being put in motion the frame and staveare pressed. against the saw F, which, being in rapid revolution, cutsoft' the surplus length, as may readily be understood on inspection ofthe drawings.

L L Lll are three uprights, risingt'roin bench A A, for the support ofthe various parts connected with dressing the sides and edges ot'staves. The three uprights are strengthened and jointed together at topby the plate M. The uprights L L are grooved. on the inside, and thesash N is madeto slide vertically in the grooves. This sash isperforated in the head, as at g, Fig. 3, and is furnished with twoplates, h It, between which the toothedquadrant j is pivoted. Thisquadrant j has ahandle or lever, i, attached for convenience of`handling. On the top ot sash N and between the plates li h the rack 7cis laid, and from the lower side ot' this rack the pointed bar or toothl projects down through the opening g in head of sash. A cord, in,attached to sash N, and passing over the pulley n, and weighted at theother end, w, tends to uphold the sash. The hand-lever O, pivoted on thelower bar of sash N and catching into the notches a in upright P,behind, enables thev sash to be depressed forcibly, notch by notch, bythe hand of the operator.

Q Q are the two bits or knives, curved to suit the periphery of barrelwhich the staves are to form. These bits or knives are laid, edgeupward, across the main beams A A. They are held apart at the properdistance and have the proper set given them by means of the wedges w to,which are driven up through the main' beams A A. The setscrews o o,which are sustained by the metal is for the purpose ofsplitting theconvex Shaying which comes off the inside of stave, and t thus preventsit curling up and blocking up the bench.

The operation of this part ofthe lnachineisv as follows: The stave,after being cut to the proper length by the saw, is placed edgewisebetween the two bits or knives Q Q, and is held slight-l) off theperpendicular by the point l, which, by means ot' the rack and arm i',is driven into the end of stave. The workman th en,bymeaus of his` handon the levert), forces the sash downward, and the stave issimultaneously forced through the two bits Q Q. As soon as the stave hasreached the middle of its length, the arm t' and point Il are changed soas to throw the stave out of the perpendicular in the oppositedirection. 'lhe lever is again worked, and the other half of the staveis lor-eed through between the knives and falls out at the bottom,dressed on both sides, and having the proper curvature both crosswiseand lengthwise. It only requires dressing now on the edges. The nextportion ofthe machine is for this purpose. I

L L", the two uprights, are grooved on their inner sides, and in thegrooves the sash R slides.V This sash is sustained by two rods, z z,which are secured to crosshead of sash by nuts, and pass up through theplate M, and through the center of two spiral springs, q q, beingjoinedat top by the box-bar 1. To the bottom of sash lt two rods, s s, areattached, and the other extremities of said rods being linked to thepedal S the operator can depress the sash li by means of hisfoot, thesprings q q returning it upward when the pressure of the foot isremoved. Across the back of sash lt a strong iron bar or plate, t, issecured, and across the front of said sash the knife-blade T (shaped asshown) is secured in both cases by screw-bolts and nuts. Three screws, uu a, riveted to blade of knife T, pass backward through the bar t, andscrew-nuts being run on the screws the knife is set to any curve whichis required by the size and taper of the barrel for which staves arebeing manufactured. v

U is a cross-piece or bench secured to and between the uprights L' L,and a small distance above the main bench-piece A A. This cross-piece iscut out or lowered in the middle to the length of the. opening in sashR, as shown, and is edged by iron plates c. On the under side of samecross-piece, a plate, 2, is secured, and through this plate, upward and.through cross-piece U, the two set-screws 3 3 are passed. The points ofthese screws are stopped by the plates 4 4, which are hinged on the ironplates t. The use of the plates 4 4 and set-screws 3 3 is to cant thestave when it is laid on thebench, so as to have the edges cut at theproper bevel for the radius of the barrel. Through between thel plate 2and under side of cross piece U niortises are cut for the bars 5 5 toslip in. These bars bear the cross-piece V, which is secured to bars,and

thus is guided in being drawn in and out from cross-piece U. `On top ofthe latter piece, V, the two projecting stops 6 are secured, and onthese the stave to be dressed on the edge is laid. The bent holder W ishinged on piece V, so as to enablethe operator to hold down the stavewhen laid on. The stave and crosspiece Vare then pushed in toward thebench U and knife, the pieces or plates 4 4 tilting saidstavejustsufliciently. Then, whenitis brought under the knife T, thepedal S is pressed down and the edge of stave is eut by knife T, and thestave is reversed for the other edge to be dressed in like manner.

The operation of this part, as well as that of the whole, having beendescribed in describing the parts, or in special paragraph, we proceedto state what we claim as new, and what we desire to secure by LettersPatent.

We claim A stave-making machine having three differentparts or devices,oneforcutting the stave to theproperlength,anotherfor dressing the sidesof staves in proper shape, and the third for dressing the edges of thesaine, 'all combined and arranged together on one bench, and each partconsisting, substantially, of the devices land parts set forth in thisspecification.
